REVERSIBLE WINDOW-SASI-I.

Specification of Letters Patent.

Patented Mar. at, ieri?.

To all whom t may concern.'

Be it known that I, Monnm BRAND, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements 'in Reversible TvVindow-Sashes, of which the following is a specilication.

This invention has for its Objects others to provide a simplied and improved form of reversible window sash, to be made of metal or wood, or a combination of the two materials, and sol constructed that the upper and lower sashes are made reversible and adapted to be raised or lowered without coniicting one with the other and adapted to be placed in any stand ard window frame and operated by the com-4 mon sash cord with weights attached; or

CIK

in any double hung, or easement, or transom or, in fact, any style of window except circular.

It has for a further object to provide such a form of reversible sash as shall do away with all shoes, blocks or rollers connected with braces and operated in grooves or channels and which will not come in contact with the window shades, curtains or draperies, thereby leaving them unsoiled, and allowing the air free inlet and 'which shall act also as a window-shield in protecting the curtains and draperies.

My improved reversible sash can be hung to operate by being attached to either the side stiles or top and bottom rails and hung from the top down instead 'of from the bottom up, by reversing stile plates.

Other objects and. advantages of the invention will hereinafter appear and the novel features thereof will be particularly pointed out in the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the numerals of reference marked thereon, form a part of this specification, and in which* Figure l is a perspective view showing the application of my present invention, the upper and lower sashes being swung into different positions.

Fig. 2 is a substantially central vertical section through Fig. 1 with the sashes indicated in their partially opened positions by dotted lines.

Fig. 3 is a section on the line 3-3 of Fig. 4, looking in the direction of the arrows.

amongl Fig. 4 is a perspective view of one set of link connections for the sashes.

Fig. 5 is an enlarged perspective view, showing one of the sashes in open position.

Fig. 6 is a similar view, showing the sash hung to the top and bottom rails instead of to the side stiles.

' Like numerals of reference indicate like yparts throughout the different views.

It is to be noted that the links are of unequal length, the shorter length being pivoted to the frame or 4equivalent fixed part at a point substantially opposite the midlength of the sash in its closed position. In one position of the sash and in reversing the links cross each other.

eferring to the drawings,

1 indicates a window frame in which are mounted to slide in the usual manner the upper and lower sash frames 2 and 3. Each frame is rabbeted, as shown at 4, and in this rabbet is disposed the sash 5 which has secured therein in any well-known way the glass 6. As shown clearly in Figs. 1

, and 4:, there is secured within the rabbet l upon each side of the frame 3, a metallic plate aiiiXed in position by screws or any othersuitable means and near each end of each plate there is pivotally connected, as at 8 and 9 respectively, the links 10 and 11, the other ends" of which links 10 and 11 are pivotally connected, as at 12 and 13, with a metallic plate 14 which is secured to the outer face of the side stile of the sash 5, it being understood, of course, that there is one of these plates and a pair of links 10 and 11 upon each side of the sash, as will e readily understood upon reference to Fig. l. I may sometimes dispense with the plate 14 and pivot the ends of the links 10 and 11 directly to the side stile of the sash, as seen at the upper sash in Fig. 1.

A sash applied as above described can be readily turned into almost any desired position. It can be thrown out any desired angle thereto to act as a window-shield or guard, or it may be reversed and brought into the position shown in the upper part of Fig. 2 so as to bring the outer face of the glass innermost. In window washing, this last feature will be found almost invaluable, as the washer doesnot have to get on the outside of the building or to be secured or strapped in any way, but has each side of side, and, furthermore,y no water can get to the inside of the room Vfrom the glass as the sash, in washing, can be placed from three to six inches away from the window threshold.Y NoV stepladder is required to wash or renew the glass, as the lower sash can be raised up out of the way, and the upper sash lowered to operate on.

My improved reversible window sash is made waterproof, the top and bottom rails having sharp bevels, and the top rail of the upper sash being made substantially of an inverted V-shaped form, as seen at 15 in Figs. 1 and 2, fitting into a corresponding recess 16 in the adjacent face of the frame 2.

It is to be understood that when the sashes 5 are in their closed position, they may be moved up and down with the frames 4 in the usual manner. Y

Any suitable means, such as handles 17, may be applied to the sash 5 for the purpose of manipulating the same. The sashes move easily and there is practically no strain on the braces or links 10 and 11.

The sashes in either their normal or reversed position may bey disposed at any required angle with relation to the frame inI which they are mounted. Y

In Fig. 6 I have shown the sash as pivotally connected with the top and bottom rails of the frame 4; instead of the side stiles. In this form the sash 5a is mounted to close within the rabbet within the frame 4a, the links 18 and 19V being pivotally connected at one end, as at 2O and 21 respectively, to the top rail of the sash and their other ends correspondingly pivoted within the rabbet of the top rail of the frame. Thebottom links 22 and 23 are pivotally mounted, as at 241 and 25 to the plate 26 secured within the rabbet of the bottom railof the frame, while the other ends of said links are pivotally connected' to the under side of the bottom rail ofthe sash, as will be readily understood. The sash thus hung is capable of being reversed or moved to any desired angle,

the same as the form shown in the other ligures, except, of course, the movement is in a horizontal instead of in a vertical plane. The top rail of the sash is made substantially V-shaped, as seen at 27, to it a correspondingly shaped recess in the adjacent top rail of the frame similar to the construction shown in Fig. 2 and for a like purpose.

Modifications in details may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages.

What is claimed as new is 1. A sash, and two links of unequal lengths each pivoted at one end to the frame and the other ends pivoted to the sash at different points, said links being disconnected from each other and arranged to allow of reversal of the sash and to cross each other in one position of the sash.

2. A sash, and two links of unequal lengths each pivoted at one end to the frame and the other ends pivoted to the sash at diiferent points, said links being disconnected from each other and arranged to allow of reversal of the sash and to cross each other yin one position of the sash, the shorter link being pivoted to the frame at a point substantially opposite the mid-length of the sash in its closed position.

3. A sash, and two links of unequal lengths upon each side thereof, said links being each pivoted at one end to the frame within which the sash is closable and having their other ends pivoted to the edges of the sash at diiferent points, the links upon each edge being disconnected from each other and arranged to allow of reversal of the sash, with the links upon each edge adapted to cross each other in the reversal of the sash.

In testimony whereof I ai'liX my signature in the presence of two witnesses.

MORRIE BRAND.
